哈尔滨理工大学工学硕士学位论文 300T免烧型制砖机设计及PLC控制的应用研究摘要为了保护环境和减少土地资源的浪费,大力推广使用免烧砖瓦是势在必行,因此,研制新型高效能的免烧型制砖机,其意义是比较深远的。本文根据课题的开发研究任务,详细调研和探讨了目前国内外免烧型制砖机的发展现状与展望,根据国内外免烧型制砖机发展经验和委托单位提出的设计要求,确定了整个系统由执行机构、液压泵站系统及PLC控制系统等组成。本文研究了免烧型制砖机的工作原理和结构组成,确定了将上料、压砖、落砖等机构设计在两个垂直面内。应用UG对免烧型制砖机执行机构和液压泵站进行了三维建模和装配,并进行了的运动学仿真研究;针对目前国内使用的大多数压砖机存在抗冲击能力差、零部件需经常更换等缺陷。确定了免烧型制砖机执行机构的动力由液压泵站系统提供,并根据该机的工作过程进行了详细的设计计算,确保整个系统的稳定、高效工作;由于要求机器实现全程自动控制,本文根据对各种控制方案的分析比较,确定了免烧型制砖机由可编程序控制器(PLC)控制,根据设备的工作流程及系统的控制要求进行了PLC的I/O分配,设计了控制程序。以上研究表明:用UG软件对免烧型制砖机进行仿真是成功的,液压控制技术与PLC技术相结合,使液压系统可更加精确、灵活地完成预期控制任务。该新型免烧型制砖机具有结构紧凑、抗冲击能力强、工作平稳等特点,达到了预期的设计目标。关键词免烧型制砖机;液压泵站;PLC;UG;运动模拟 Application Research ofDesign and PLC Control On 300T Non..burned Brick Machine Abstract In order toprotect theenvironment andreduce waste ofland resource,it is imperative thatthe use ofnon—burned bricks and tilesarepromoted vigorously, therefore,it isquite profound fordevelopment of new high-performance non。 burned brickmachine. According to thework of theexploitation ofthissubject,the developing situation and outlook ofdomestic and foreign ofnon—burned brick have been investigated and studied indetail.In thelight ofdeveloping experiences of domestic andforeign ofnon.burned brickand thedesign requirements which missioned unitproposed,the overall system which hasbeen determined posed oftheactuator,hydraulic pump stationsystem andPLC controlsystem· Inthispaper,working principal and structure ofnon。burned machine have been studied indetail.we have determined thatmake theappending part,the brick pressing part and thebrick dropping part lay on thetwo perpendicular planes,the actuator and hydraulic pump station ofnon—kiln brick machine pleted on thebase ofUG and thekinematics simulation isalsoresearched. presently,most domestic brick machine has some defects,for example,the impact islow,replacement parts are oftenneeded.we have determined thatthe power ofthe actuator ofnon—burned brick isoffered by the hydraulic pump system.and the detaileddesign and calculation hasbeen carried on according to thismachine work process inorder to ensure thestability ofentiresystem and make thesystem work efficiently.according parison ofeach kind of control plan in thispaper'the non.burned brick machine iscontrolled by programmable ontrol(PLC)to satisfy therequirement ofautomatic control, The I/O ofPLC have been assigned according tothecontrol request ofsystem and work flow ofequipment,the contr01 procedure has designed. As shown inthethesis,the simulation ofUG essful.through the .n. bination ofhydraulic control technologies and PLC technologies.Thereby the hydraulic system Call plish anticipative controlarrangement more exactly and more skillfully.the new non-burned brick machine has reached the expected goal,which hasthepossesion ofsuch advantages pact structure, strongimpact and steady work.
